Abstract: CA 02961104 2017-03-10 = PCT/CN2015/081310 ENGLISH TRANSLATION ABSTRACT A rotating magnetic field rangefinder for measuring relative distance in drilling, comprising a permanent magnet steel drill collar (1), an underground detector (2) and a ground interface box (3). The permanent magnet steel drill collar (1) is fixed to the rear part of a drill bit and rotates together with the drill bit to generate a rotating magnetic field to provide a magnetic field signal source. The underground detector (2) comprises two tri-axial fluxgates and three accelerometers. The ground interface box (3) is used for processing the obtained data, and powering the underground detector. The permanent magnet steel drill collar (1) is an obliquely arranged one or a perpendicularly-and-parallelly assembled one. A measuring method for magnetic range measurement is also disclosed. The magnetic field rangefinder and the measuring method can directly measure the relative position of the drill bit and a target spot, thereby avoiding error accumulation, and achieving the accurate measurement of the relative position of the drill bit and the spot. 28

Abstract: Il est décrit des méthodes et des trousses servant à isoler des acides nucléiques dont la taille est supérieure à une taille maximum dans un échantillon chargé dacide nucléique. La méthode en question consiste à combiner léchantillon à un tampon liant, de lalcool et du carbure de silicium en vue de produire un mélange liant. Les acides nucléiques de taille supérieure à la taille maximum se lient de manière sélective au carbure de silicium. La détermination de la taille maximum en ce qui concerne la liaison sélective au carbure de silicium dépend de la concentration dalcool dans le mélange liant. Les acides nucléiques liés sont séparés de léchantillon restant. Les acides nucléiques liés sont facultativement nettoyés, puis élués du carbure de silicium. La trousse comprend un agent liant tampon conçu pour se diluer dans lalcool en vue dobtenir une concentration dalcool entre 1 % et 50 % (v/v) environ, une solution de nettoyage, une solution délution, du carbure de silicium et des instructions quant à la façon de modifier la concentration dalcool en vue de lier de manière sélective des acides nucléiques de taille supérieure à une taille maximum.
